We look at the division of 86759877 by 654 
The aim is to understand the frequency of 654 in 86759877.

Moving on to step 1:
The number 654 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 654

On to step 2:
654 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 654

Moving on to step 3:
654 can be fit into 867 1 times, resulting in a remainder of 213.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 654 from 867 and we're left with 213.
Take the next digit (5) from the dividend and append it to 213, then repeat: 2135 / 654

Step 4:
If we divide 2135 by 654, we get 3 and a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 1962 from 2135 to get 173.
Bring next digit (9) of the dividend behind the 173 and repeat the process: 1739 / 654

On to step 5:
If we divide 1739 by 654, we get 2 and a remainder of 431.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
Subtract 1308 from 1739 to get 431.
Grab the next digit (8) from the dividend, add it to 431, then carry on: 4318 / 654

Step 6:
When dividing 4318 by 654, we get 6 with a remainder of 394.
Write down 6 as next digit of the result. 
Result so far: 1326.0
Subtracting 3924 from 4318 leaves us with 394.
Include the next digit (7) from the dividend after 394, then repeat: 3947 / 654

Advancing to step 7:
When dividing 3947 by 654, we get 6 with a remainder of 23.
Write down 6 as next digit of the result. 
Result so far: 13266.0
Subtracting 3924 from 3947 leaves us with 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 654

Moving on to step 8:
When dividing 237 by 654, we get 0 with a remainder of 237.
Use 0 as the next digit of our solution. 
Result so far: 132660.0
The remainder is 237 after subtracting 0 from 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 9:
654 goes into 2370 3 times with a remainder of 408.
The next digit of our result is 3. 
Result so far: 132660.3
Deduct 1962 from 2370 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 10:
4080 divided by 654 is 6 with a remainder of 156.
The next digit of our result is 6. 
Result so far: 132660.36
The remainder is 156 after subtracting 3924 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
654 can be fit into 1560 2 times, resulting in a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 132660.362
Subtract 1308 from 1560 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 12:
654 goes into 2520 3 times with a remainder of 558.
Write down 3 as next digit of the result. 
Result so far: 132660.3623
Deduct 1962 from 2520 and we're left with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 13:
654 can be fit into 5580 8 times, resulting in a remainder of 348.
Use 8 as the next digit of our solution. 
Result so far: 132660.36238
Deduct 5232 from 5580 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Moving on to step 14:
654 goes into 3480 5 times with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 132660.362385
If we subtract 3270 from 3480, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 15:
654 goes into 2100 3 times with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 132660.3623853
The remainder is 138 after subtracting 1962 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 16:
654 can be fit into 1380 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 132660.36238532
Deduct 1308 from 1380 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 132660.36238532, and the remainder is 7.2e-08.
